Is 3.2 mm a year still the right rate for global sea-level rise?
oceandata.net/sea-level says sea level is rising “by about 3.2 mm per year”. As far as I can tell that is the 1993–2010 average. Is there a more current figure the page should use?
oceandata.net/sea-level · see its record3.2 mm is the 1993–2010 average. The current figure is 3.7 mm per year for 2006–2018, and the rate is accelerating. Give the figure with its period.

Agree. WG1 chapter 9, section 9.6 has the table. I’d also add “and accelerating” so the number doesn’t read as constant.
Thanks both. We’ve received the correction from this thread and will decide this week.
